"And why do black people seem to have so much difficulty making clothes for themselves, building schools for themselves, doing much of anything expected of any group of people."

They don't. That is your discrimination in action. Clothes, schools, and the rest are what a functioning society produces. They are members of this society, therefore they produce all these things. Hence, they should not be prohibited from any of it.

Maybe, just maybe, if we're lucky, this is the start of a new era, where haters and bigots and willfully ignorant people, espcecially homophobes, and teaparty nitwits, will begin to be marginalized. We can only hope.
